Somerset, England, 1888. A land and a community on the edge of monumental change, on the great hinge between ancient traditional ways and an industrial, scientific future. A land of ghosts and myths, poltergeists and demons – if there was ever a time for those ghosts to rise out of the ground, this would be that time. At the heart of this small community is Nathan Appleby, a reluctant gentleman farmer who is obsessed with proving the existence of the afterlife.

In BBC One’s new original drama this complex and compelling man will investigate hauntings, paranormal happenings, and ghostly visitations, encouraged by the Society for Psychical Research. But as these terrifying investigations become ever more frequent and ever more scary, Nathan starts to see and hear disturbing things that he simply cannot have imagined. Will Nathan’s interest in the occult begin to threaten his family, his livelihood and even his sanity?
